Narrated by Abdullah (r.a), Allah’s Messenger (peace be upon him ) said:-

“(As regards to your creation), every one of you is collected in the womb of his mother for the first 40 days, and then he becomes a clot for another 40 days, and then a piece of flesh for another 40 days. Then Allah (s.w.t) sends an angel to write 4 words: He writes his deeds, time of his death, means of his livelihood, and whether he will be wretched or blessed (in the Hereafter). Then the soul is breathed into his body. So a man may do deeds characteristic of the people of the (Hell) Fire, so much so that there is only the distance of a cubit between him and it, and then what has been written (by the angel) surpasses; and so he starts doing deeds characteristic of the people of Paradise and enters Paradise. Similarly, a person may do deeds characteristic of the people of Paradise, so much so that there is only the distance of a cubit between him and it, and then what has been written (by the angel) surpasses, and he starts doing deeds of the people of the (Hell) fire and enters the (Hell) Fire.”

Once Prophet Ibrahim / Abraham (pbuh) asked Malakul Maut, Hazrat Izrael (the angel of death) to show their form with which they appear in front of the one who is being departed, a believer and a sinner.

Malakul Maut asked Prophet Ibrahim / Abraham (pbuh) to turn around. And when Prophet Ibrahim / Abraham (pbuh) turned back and looked at Malakul Maut, he said, 'O Izrael! If a person saw you in this state, he will certainly faint.' indicating the horror of their appearance that they looked fierce and balls of fire were coming out from each of their hair.

Then, Malakul Maut asked Prophet Ibrahim / Abraham (pbuh) to turn around. And when he looked at Malakul Maut this time said, 'O Izrael! If a crying person saw you in this state, he will start smiling.'

This is all narrated in the following sound hadith of the prophet (saw): "When the believer is about to depart from this world and go forward into the Next World, angels with faces as bright as the sun descend from the heavens and sit around him in throngs stretching as far as the eye can see. Then the Angel of Death comes and sits at his head and says, "Good soul, come out to forgiveness and pleasure from Allah!" Then his soul emerges like a drop of water flows from awater-skin and the angel takes hold of it. When he has grasped it, the other angels do not leave it in his hand even for the twinkling of an eye. They take it and place it in a perfumed shroud and fragrance issues from it like the sweetest scent of musk found on the face of the earth.'

It was narrated that al-Bara’ (may Allaah be pleased with him) said: We went out with the Messenger of Allaah (peace and blessings of Allaah be upon him) for the funeral of a man from among the Ansaar. We came to the grave and when (the deceased) was placed in the lahd, the Messenger of Allaah (peace and blessings of Allaah be upon him) sat down and we sat around him, as if there were birds on our heads (i.e., quiet and still). In his hand he had a stick with which he was scratching the ground. Then he raised his head and said, “Seek refuge with Allaah from the torment of the grave”, two or three times. Then he said, “When the believing slave is about to depart this world and enter the Hereafter, there come down to him from heaven angels with white faces like the sun, and they sit around him as far as the eye can see. They bring with them shrouds from Paradise and perfumes from Paradise. Then the Angel of Death comes and sits by his head, and he says, ‘O good soul, come forth to forgiveness from Allaah and His pleasure.’ Then it comes out easily like a drop of water from the the mouth of a waterskin. When he seizes it, they do not leave it in his hand for an instant before they take it and put it in that shroud with that perfume, and there comes from it a fragrance like the finest musk on the face of the earth. Then they ascend and they do not pass by any group of angels but they say, ‘Who is this good soul?’ and they say, ‘It is So and so the son of So and so, calling him by the best names by which he was known in this world, until they reach the lowest heaven. They ask for it to be opened to them and it is opened, and (the soul) is welcomed and accompanied to the next heaven by those who are closest to Allaah, until they reach the seventh heaven. Then Allaah says: ‘Record the book of My slave in ‘Illiyoon in the seventh heaven, and return him to the earth, for from it I created them, to it I will return them and from it I will bring them forth once again.’ So his soul is returned to his body and there come to him two angels who make him sit up and they say to him, ‘Who is your Lord?’ He says, ‘Allaah.’ They say, ‘What is your religion?’ He says, ‘My religion is Islam.’ They say, ‘Who is this man who was sent among you?’ He says, ‘He is the Messenger of Allaah (peace and blessings of Allaah be upon him).’ They say, ‘What did you do?’ He says, ‘I read the Book of Allaah and I believed in it.’ Then a voice calls out from heaven, ‘My slave has spoken the truth, so prepare for him a bed from Paradise and clothe him from Paradise, and open for him a gate to Paradise.’ Then there comes to him some of its fragrance, and his grave is made wide, as far as he can see. Then there comes to him a man with a handsome face and handsome clothes, and a good fragrance, who says, ‘Receive the glad tidings that will bring you joy this day.’ He says, ‘Who are you? Your face is a face which brings glad tidings.’ He says, ‘I am your righteous deeds.’ He says, ‘O Lord, hasten the Hour so that I may return to my family and my wealth.’ But when the disbelieving slave is about to depart this world and enter the Hereafter, there come down to him from heaven angels with black faces, bringing sackcloth, and they sit around him as far as the eye can see. Then the Angel of Death comes and sits by his head, and he says, ‘O evil soul, come forth to the wrath of Allaah and His anger.’ Then his soul disperses inside his body, then comes out cutting the veins and nerves, like a skewer passing through wet wool. When he seizes it, they do not leave it in his hand for an instant before they take it and put it in that sackcloth, and there comes from it a stench like the foulest stench of a dead body on the face of the earth. Then they ascend and they do not pass by any group of angels but they say, ‘Who is this evil soul?’ and they say, ‘It is So and so the son of So and so, calling him by the worst names by which he was known in this world, until they reach the lowest heaven. They ask for it to be opened to them and it is not opened.” Then the Messenger of Allaah (peace and blessings of Allaah be upon him) recited (interpretation of the meaning):

He said: “Then his soul is returned to his body, and there come to him two angels who make him sit up and they say to him, ‘Who is your Lord?’ He says, ‘Oh, oh, I don’t know.’ They say, ‘What is your religion?’ He says, ‘Oh, oh, I don’t know.’ Then a voice calls out from heaven, ‘Prepare for him a bed from Hell and clothe him from Hell, and open for him a gate to Hell.’ Then there comes to him some of its heat and hot winds, and his grave is constricted and compresses him until his ribs interlock. Then there comes to him a man with an ugly face and ugly clothes, and a foul stench, who says, ‘Receive the bad news, this is the day that you were promised.’ He says, ‘Who are you? Your face is a face which forebodes evil.’ He says, ‘I am your evil deeds.’ He says, ‘O Lord, do not let the Hour come, do not let the Hour come.’”

Narrated by Abu Dawood, 4753; Ahmad, 18063 – this version was narrated by him. Classed as saheeh by al-Albaani in Saheeh al-Jaami’, 1676.

From them is what Abu Dawud transmitted from Abu Hurayrah (Allah be pleased with him) through another route in marfu’ form: “None sends peace on me but Allah restores to me my soul so I can respond to him [by sending him] peace”. Its narrators are trustworthy as al-Hafiz clarified in al-Fath. It may be problematised by [claiming that] the restoration of the soul to the body entails that it was previously detached from the body, which is death, so the hadith only proves that the soul returns upon sending peace.

imam al-Bayhaqi (Allah have mercy on him) responded to this problem in his treatise on the life of the Prophets (p. 5) by his saying: “He only intended, and Allah knows best, ‘and Allah restored to me my soul so I [am able to] respond to him by sending peace.’” Its upshot is that the assumption in the expression is : “None sends peace on me but Allah has restored to me my soul before that so I can respond to him.” Hence, his statement (Allah bless him and grant him peace) “Allah restored to me my soul” is in the context of responding to a greeting, and the intended meaning is that “I respond to him by sending peace (upon him) due to my soul having already been restored to my body.”

Entering the grave: When the body is buried, the soul stays beside the body and sees the horrifying unseen world.

Squeezing or pressure of the grave: When people leave the gravesite, angels come to squeeze the soul fiercely, making it scream loudly. Few souls are exempted from this punishment.

Munkar and Nakeer: These two angels come after the squeezing and question the soul about the beliefs of his faith. If the soul does not answer properly and was a wrongdoer in life, then he will be punished in the hellfire of the unseen world until the Day of Judgment or until his sins are purged. If the person was a pious true believer, then he will answer the questions properly and two angels of glad tidings will come to escort him to the Paradise of the unseen world.

(1) Narrated 'Abdullah bin Abi Qatada: My father said, "One night we were traveling with the Prophet and some people said, 'We wish that Allah's Apostle would take a rest along with us during the last hours of the night.' He said, 'I am afraid that you will sleep and miss the (Fajr) prayer.' Bilal said, 'I will make you get up.' So all slept and Bilal rested his back against his Rahila and he too was overwhelmed (by sleep) and slept. The Prophet got up when the edge of the sun had risen and said, 'O Bilal! What about your statement?' He replied, 'I have never slept such a sleep.' The Prophet said, 'Allah captured your souls when He wished, and released them when He wished. O Bilal! Get up and pronounce the Adhan for the prayer.' The Prophet performed ablution and when the sun came up and became bright, he stood up and prayed." (Book #10, Hadith #569)

Sahi Bukhari: 13:115: “A well-dressed soul may be naked hereafter for not praying in time…”

Sahi Muslim-20:4651:”The souls of the martyrs live in the bodies of green birds who have their nests in the chandeliers hung from the throne of Allah; they eat the fruits of paradise; they would request Allah to return their souls to their bodies so that they may be slain in the path of Allah again…”
